The Basics Of Check Valves Pumps Systems
This style of check valve is a good choice in applications that have a high percentage of solids and a lower onoff cycle count.Due to the travel distance of the disc, swing check valves close slowly.This causes the last push of reverse flow to slam the disc closed, resulting in a huge pressure spike, causing water hammer.Back to basics.
